Phytoseiid mites (Acari: Phytoseiidae) associated with tropical ornamental plants, with a checklist and a key to the species of Bahia, Brazil.

Twenty-four papers refer to phytoseiid mites from different plant species in the state of Bahia, northeastern Brazil, but none of those refer to taxonomic surveys on ornamental plants. The aim of this study was to determine phytoseiids from tropical ornamentals in the southern coastal region of Bahia state, as well as to present a checklist and an identification key to the species recorded in that state. Samples were collected at eight localities of five municipalities. A total of seventeen species in nine genera was found on fifteen plant species of the families Costaceae, Heliconiaceae, Musaceae and Zingiberaceae. The most frequent and abundant phytoseiid species were Iphiseiodes metapodalis (El-Banhawy), Amblyseius operculatus De Leon and Iphiseiodes zuluagai Denmark & Muma, respectively. The checklist and the identification key to the Phytoseiidae species of Bahia were prepared based on the published literature.
